| 摘 要： | 应用高效液相色谱研究异双官能团（VS／MCT）型活性染料C．I．Reactive Blue194在不同条件下的水解行为及其水解动力学，结果表明：C．I.Reactive Blue194的两个活性基VS和MCT在碱性下均发生水解，染料的主要水解产物有3种，即染料的VS、MCT活性基分别被水解及同时被水解的产物；同时，染料的水解过程中还伴随有亚胺基桥基的断裂。研究同时证实了C．I．Reactive Blue194的总水解反应为准一级动力学反应，随着pH和温度的增加，染料水解速率递增。

| Abstract: | The research uses high performance liquid chromatography to study hydrolysis behavior and hydrolysis kinetics of mixed hifunctional（VS/MCT）reactive dyes--C. I. Reactive Blue 194 in different conditions. The results show that： the two activity group（VS/MCT） of C. I. Reactive Blue 194 are hydro- lyzed under alkaline condition. There are three kinds of main hydrolysis products which are hydrolyzed by VS, MCT and both; simultaneously, the process of hydrolysis is accompanied by the fracture of imino bridge. The study also confirms that the hydrolysis of C. I. Reactive Blue 194 is a pseudo first-order reaction as long. With the increase of pH value and temperature, the hydrolysis rate of dye increases. |
